TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY J. DILL, of Cummngton, in the .county ofHampshire, and State of Mussucliu` setts,` have invented a new anduseful Improvement in Saw-Bucks; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable those skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part ot' thisspecification.

This invention relates to the manner in which a stick ot' {ire-wood orcord-wood is held fast or secured in the saw-buck for the purpose ofsawing it into suitable lengths; undfit consists in arranging adjustabletoothed clamps for holding the stick, which clamps nre brought incontact with it by bearing upon a treadle with the foot, and whichclamps are thrown apart by the action of springs, as will be hereinafterdescribed.

Figure 1 represents a side view of' the saw-buck with the clampsattached. l p y Figure 2 is an end view, showing more distinctlytheditl'erent parts, andthe manner oftheir combination.

Similar letters of reference indicate corresponding parts. p

A represents the stands of an ordinary saw-buck, connected `together bythe bar B in the usual manner. They 'are also connected by another baror rod at their lower ends, which rod is marked C. D represents theclamps. There are two of these, as seen in the drawing, each formed oftwo pieces, which :1re halved together where they intersect each other,and with the bar B passing through them, as seen, which bar forms apivot, l

upon whichthey hang, and turn or open and shut like a pair of shears.Each of those clamps has an arm, E, which is fast to one leg, and whichpasses through. a mortise in the other leg, as seen, and around this armthere is a spiral spring, F', the tension of which tends to keep thelegs apart.' In order to draw them together, and thereby bring the jawstogether, a treadle, E', is attached tothe lower bar or rod, C, by ahinge, a. F represents rods, which are attached to each of the four legsofthe clamp by staples, the endsof which rods are attached to rings, asseen in the drawing. Theserings support a rod, over which the trendlepasses, and which is depressed by bearing or pressing upon the treadle,and raised by the action of the springs, when the pressure upon thetreadle is removed. In this way 'the clamps are made to gripe a stick ofwood, as seen in `ig.'2. Gr represents the wood. For the purpose-ofholding the wood more firmly, thejaws of the clamps are provided withteeth or spikes, which penetrate the wood when the jaws approach eachother, and hold it fast. I

Having thus described my invention= I claim as new, and desireto secureby Letters Patent- The clamps D, the treadle E', the arms E, springs F',sind rods F, constructed, arranged, and operating,

in combination with the stationary part A, substantially as shown unddescribed, for the purpose set forth.
